I own a 3.0 manual here in the UK (South Wales) I need a new gearbox apparently 😣 does anyone know where I can get a replacement or refurbished one etc?
Really don't want to get another car as I love it.
Regards,

Reason: Amend thread title
Have you tried checking with a breaker as they can locate a used gearbox for you. Your vehicle appears to be a facelift model, so is fitted with the ZF 6HP26.
What is wrong with the gearbox in the vehicle? Has it been serviced?

Whirring noise in 1-4th under acceleration, mainly coming from under the centre of the car, then at 55-70+ drone from where I imagine the prop shaft(s)/diff is. Still changes gear fine etc but garage says I need to replace it. My thoughts initially were it's the socket joint on the propshaft that you ffeel right the way through to the gear lever. Garage said no it's the gearbox.

Has the gearbox ever been serviced? ZF recommend changing the pan/filter and fluid every 100,000 km/60,000 miles to prolong its life.
Find another garage or Jaguar specialist for a second opinion prior to replacing the gearbox. The rear differentials have a tendency to exhibit bearing wear causing a similar noise.

I must apologise, I reread your post and missed that you have a manual gearbox. What was the condition of the fluid? Are there any metal shards visible?
Surely if there's wear to the layshaft bearings, which would make a noise in first through fourth gear, the bearings can be replaced. Is there any noise at idle with the clutch pedal released that goes away when the pedal is depressed? If so the input shaft bearing is worn.

I've amended your thread title which I see has been causing some confusion! I've also added vehicle details to your forum signature so they will dispaly automatically unless you choose to change the setting.

Okay well I bought some oil so I will do a change and see. Hopefully no metal shards🙏
Going to have a go now and listen at idle clutch depressed etc, thank you so much.
So I've just changed the oil for a 75w90 about 1.6ltr.
The oil was very dark and did contain a small amount of what I can describe as copper particles or a light metal. They were microscopic and not noticible untill a shimmer would revealed them.
I added a tube of moly slip.
Changes are smoother although not a whole lot of difference. Whirring under acceleration noise is quieter. But is still there. Doesn't make any noise in neutral with clutch depressed. Humming coming from rear is still there I'm 90% sure is a wheel bearing or uneven tyre. So that brings us back to the whirring noise under the gear lever. It's still not there in 5th. But present in 1-4. Gear changes are fine and it never slips a gear or feels clunky.. I am starting to think if I replace the gearbox it may still be there because apart from the whirring noise it's seems fine.
If the whirring noise disappears when the clutch pedal is depressed, that usually indicates a worn input shaft bearing.
If the whirring noise is present in gears one through four, but not in fifth, that usually indicates worn layshaft bearings as fifth is direct drive through the gearbox.

So 1-4 are using both main and lay but 5th is straight on the main and as such doesn't need to use the layshaft? Thank you. That's helped me visualise it. I either get them replaced or I get a refurbished one. But at least I have a pretty good idea of what it probably is. I am thinking I want to change to a lighter flywheel so might as well as it's out. And a few other things over the next year or so. Getting into tig welding so want to do a titanium cat back at some point maybe even a cage.. I recently came across an image of an s-type V8 star.... Got me dreaming/thinking I could spend a bit of 💰 and blueprint the engine upgrade the suspension and add some lightness. As a cad-cam guy I could.actually do the body work myself.
Yes, that is correct. Fifth is directly locked to the input shaft. The bright flecks of metal are usually from the brass blocker rings. Steel particles are from the gear faces.
Some gearboxes, even in racing cars, can make odd sounds, but if they're shifting smoothly and there is no overabundance of metal in the oil, you can probably continue driving it for several thousand miles more.

Well, that's good to hear so I will book it in to have bearings & blocker rings replaced, and I'm sure I will find a few more things to do at the same time. As it's costing me already I've decided I am taking the long road and going full hog I will be building it into a track-able daily driver with v8 star body. 1st thing is to sort everything. Thank you for all the valued input. I've only had the car for a few months but I love it already. I bought it because it was a steal but didn't think I would end up enjoying it as much as I have. Coming from a 911's(993) I didn't expect it to be so much a driver's car but it truly is whether in town on a motorway or a b-road. Thanks again.
